Ntau tus pib ua haujlwm hauv lawv tsev neeg hauv lub tsev nyob rau lub caij ntuj sov lossis nyob rau hauv lub teb chaws txaus siab rau cov lus nug ntawm yuav ua li cas los tsim cov tsev. Tseeb, nyob rau hauv niaj hnub kev lag luam ntawm cov khoom siv hauv tsev muaj ntau yam ntawm cov phab ntsa thaiv, cov ntaub ntawv ntoo, thav duab siv yees. Cov khoom siv twg los xaiv los ua lub hauv paus tseem ceeb rau kev tsim lub hauv paus thiab phab ntsa ntawm lub tsev, tsev, chaw nres tsheb lossis tsev noj mov? Hauv kab lus no, peb yuav xav txog cov khoom ntawm cov khoom xws li cov xuab zeb-cement thaiv, nws cov yam ntxwv thiab kev siv.
Composition
Sand-cement wall blocks muaj cov khoom zoo Portland cement, coarse xuab zeb thiab pob zeb chips ua cov khoom tseem ceeb. Tsis tshua muaj manufacturers suav nrog plasticizers thiab lwm yam additives nyob rau hauv lawv muaj pes tsawg leeg.
Sand-cement blocks: specifications
Raws li GOST 6133-99, cov blocks no yog tsim nrog qhov ntev ntawm 390190190 thiab 400200200 mm. Lwm cov yam ntxwv muaj xws li:
• hnyav - 14-18 kg;
• thermal conductivity - 0.4-0.55 W (mC);
• lub zog - M- 35; • Frost resistance - F-25;
• thaiv ntom ntom- 940-1100 kg/m

Tsev tsim khoom
Sand-cement block yog tsim los ntawm cov xuab zeb-pob zeb sib xyaw los ntawm vibrocompression, uas txiav txim siab nws lub zog compressive siab thiab lub neej ua haujlwm ntev. Cov thev naus laus zis no muab qhov zoo tshaj plaws geometric tsis ntawm cov blocks thiab ua raws cov ntaub ntawv siv tau nrog cov yam ntxwv tshaj tawm.
Ntau yam thiab qhov zoo ntawm cov blocks
Sand-cement thaiv tuaj yeem ua tau khov lossis hollow. Muaj ob, plaub, 7 lossis 8 kab noj hniav sab hauv. Hollow thaiv cov kev xaiv muaj zog me ntsis, tab sis lawv muaj kev tiv thaiv tshav kub ntau dua thiab tsis muaj suab nrov, thiab kuj muaj qhov hnyav thiab nqi.
Sand-cement blocks 20x20x40 cm, raws li txoj cai, yog siv rau hauv kev tsim kho cov txheej txheem thauj khoom, txhawb cov kab, hauv paus, hauv qab daus phab ntsa. Cov phab ntsa tuaj yeem yog ib nrab ntawm qhov thaiv tuab, ib kab, ib-thiab-ib-ib nrab, lossis ob-thick. Vim muaj cov yam ntxwv ntawm lub zog siab thiab txaus siab thermal rwb thaiv tsev cov khoom ntawm hollow blocks nyob rau hauv lub hauv paus sawb ntawm Russia, ib leeg-kab tuab yog txaus thaum tso phab ntsa sab nraud. Cov xuab zeb-cement thaiv yog resistant rau aggressive ib puag ncig influences thiab kuj yog siv nyob rau hauv industrial tsim. Cov neeg siv khoom zoo ntawm cov blocks suav nrog:
• yooj yim ntawm cov txheej txheem masonry;
• yooj yim ntawm plastering thiab painting ntawm blocks;
• tus nqi tsim nyog;
• ib puag ncig tus phooj ywg;
• zoo suab rwb thaiv tsevthiab phab ntsa rwb thaiv tsev.
Scope of application
Sand-cement blocks tso cai rau koj los tsim cov qauv thauj khoom tshwj xeeb ntawm cov tsev, cov tsev nrog lawv cov rwb thaiv tsev ntxiv. Lawv raug pom zoo siv rau hauv kev tsim kho ntawm lub hauv paus, plinths thiab sab nrauv phab ntsa ntawm cov tsev lag luam, kev tsim kho qis thiab ntau lub tsev (ntawm cov phab ntsa tau ntim rau hauv kev tsim kho monolithic). Tso cov xuab zeb-cement blocks yog sib zog dua li tso ib qho cib. Tom qab tag nrho, qhov ntim ntawm ib qho xuab zeb-cement thaiv yog sib npaug rau qhov ntim ntawm 7 cib.
Kev tsim kho ntawm lub hauv paus thiab hauv av pem teb ntawm cov tsev los ntawm cov xuab zeb blocks muaj txiaj ntsig tshwj xeeb piv rau txoj kev nchuav. Qhov no ua rau nws muaj peev xwm tshem tawm cov txheej txheem ntawm kev npaj cov formwork thiab tam sim ntawd tom qab nteg lub hauv paus, pib nteg cov phab ntsa, tsis tas tos rau cov pob zeb teeb, uas muab ib tug tseem ceeb, tsawg kawg yog ib lub hlis, acceleration ntawm kev tsim kho ua hauj lwm.
Thaum tsim cov hauv paus thiab hauv qab daus hauv qab ntawm cov tsev, nws raug nquahu kom siv cov khoom thaiv, thiab thaum tso cov phab ntsa - hollow ones, uas txo cov nqi ntawm kev tsim kho, txhim kho cov cua sov thiab suab rwb thaiv tsev zoo ntawm phab ntsa thiab txo cov kev xav tau. rau lub hauv paus muaj zog. Rau kev teeb tsa ntawm phab ntsa, koj tuaj yeem siv tshwj xeeb faib phab ntsa xuab zeb-cement blocks nrog lub thickness txo los ntawm ib nrab. Lawv kuj muaj nyob rau hauv cov khoom los yog hollow.
Qhov kev nce nyiaj ntau dua ntawm cov nqi ntawm kev tsim kho tuaj yeem ua tiav los ntawm kev siv cov xuab zeb-cement blocks rau cov phab ntsa masonry nrog qhov sib ntxiv ntawm cov ntxeem tau. Cov ntaub ntawv - nthuav av nplaum, nplua slag, sawdust.
Zoo kawg
Kev siv cov xuab zeb-cement blocks hauv kev tsim cov tsev qis qis tuaj yeem ua haujlwm nrawm dua thaum ua tau raws li qhov yuav tsum tau ua kom sov thiab suab rwb thaiv tsev, lub zog thiab ruaj khov ntawm cov tsev. Nws yog cov yam ntxwv tshwj xeeb uas txiav txim siab lawv txoj kev siv dav hauv kev tsim kho niaj hnub no.
